Simultaneous observations of two rotational lines of methanol together with HDO in the same spectrum allow us to determine the average gas temperature within the telescope beam to be 69 +/- 10 K.

The average temperature is about -53°C. Although thin and frigid, the Martian atmosphere is very active and complex. Mars and Earth have similar global atmospheric circulation patterns.

Comets are small, fragile, irregularly shaped bodies composed of a mixture of non-volatile grains and frozen gases. ... Comet structures are diverse and very dynamic, but they all develop a

To Becklin and Westphal, this consistent temperature behavior suggests that the comet generated no heat, but was warmed entirely by solar radiation.

The average planetary temperature was around -61ºC; however at Echo Base, located near the planet's equator in the northern hemisphere, ... His starship was caught in the hyperstream of the comet,
